Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a CRT (cathode ray tube) mounting structure in a television receiver, CRT monitor device, etc.

[Prior art]

To install a CRT, integrally form CRT mounting parts at the four corners of the back of the front panel of the cabinet, and fix the mounting brackets protruding from the four corners of the CRT to the mounting parts by tightening screws. It's on.

However, if it is necessary to adjust the degree of adhesion between the front of the CRT and the front panel of the cabinet, conventionally it is necessary to individually insert a spacer or the like between the CRT bracket and the CRT mounting part, which requires a lot of work. was complicated and hot.

[Purpose of invention]

An object of the present invention is to provide a CRT mounting structure that allows the degree of closeness between the front surface of the CRT and the front panel of the cabinet to be easily adjusted.

[Structure of the idea]

This invention consists of a cylindrical CRT mounting part provided for the cabinet, a cylindrical CRT mounting body that fits into the CRT mounting part, and a CRT mounting part that is attached to the bottom of the CRT mounting part through the CRT mounting body. A CRT mounting structure comprising a mounting bracket fixed with screws, wherein concavities and convexities are formed in the cylindrical circumferential end surface of the CRT mounting portion alternately and continuously at the same pitch and at the same angular intervals in the circumferential direction, and the CRT is A concavo-convex portion identical to the concave-convex portion is formed in the circumferential direction of the flange formed on the circumference of the mounting body so as to face in a direction parallel to the axial direction, so that the convex portion of the CRT mounting portion and the concave portion of the CRT mounting body are aligned. Fit or connect the convex part of the above CRT mounting part and the above
The convex part of the CRT mounting part abuts against it.

〔Example〕

Examples of the present invention will be described below. 1st
The figure is an exploded perspective view of the mounting structure of one embodiment.
FIG. 2 is a developed view of the mounting portion for explaining the operation.

Reference numeral 1 indicates a cabinet, and CRT mounting portions 2 are provided at the four corners of the front opening (not shown) for mounting a CRT.
(Only one location is shown in FIG. 1) is formed.

This CRT mounting part 2 includes a mounting cylindrical part 21,
Ribs 22 and 23 for external reinforcement of the cylindrical portion 21
and a rib 24 for internal reinforcement, and the cylindrical part 21
Concave portions 21a and convex portions 21b having equal angular widths are alternately formed at equal angular pitches in the circumferential direction at the upper end, and guide grooves 21c are formed at the center positions inside each of the concave portions 21a and convex portions 21b. has been done. 24
A is a screw hole for mounting.

On the other hand, reference numeral 3 denotes a single CRT mounting body, which has a cylindrical portion 31 having an outer diameter that can be fitted into the cylindrical portion 21 of the CRT mounting portion 2 described above.
A tsuba 32 is formed around the central part of the tsuba 32.
Concave portions 32a and convex portions 32b having the same pitch and the same angular width as the concave portions 21a and convex portions 21b described above are alternately formed. And the recessed part 32a,
Cylindrical portion 3 on the side in the direction in which the convex portion 32b is formed
1, protrusions 31a are formed in the axial direction at positions corresponding to the centers of the recesses 32a and protrusions 32b and are equiangularly pitched with the guide grooves 21c. 31b is an insertion hole for a mounting screw.

4 is a CRT mounting bracket that protrudes from the four corners of the CRT (not shown).
Attached to CRT. 41 is a screw insertion hole.

Now, in this embodiment, by fitting the CRT mounting body 3 into the cylindrical portion 21 of the CRT mounting portion 2 from the side where the protrusion 31a is formed, and aligning the protrusion 31a with the guide groove 21c, The concave portion 32a and convex portion 32b of the CRT attachment body 3 and the CRT attachment portion 2
Regarding the recess 21a and the projection 21b, the recess 32
a and the convex part 21b, the convex part 32b and the concave part 21a
It is possible to achieve a good fit. Also, in this state, by fitting the guide groove 21c and the protrusion 31a with a one-pitch shift, the recess 32a and the recess 2
1a, the convex portions 32b and 21b can be opposed to each other.

Therefore, the mounting height of the CRT mounting body 3 to the CRT mounting portion 2 can be adjusted by the height of the above-mentioned unevenness.

The mounting bracket 4 is constructed by fitting the CRT mounting body 3 into the cylindrical portion 21 of the CRT mounting portion 2, aligning its hole 41 with 31b of the CRT mounting body 3, and inserting the mounting screw (not shown) from there. and screw it into the hole 24a of the CRT mounting part 2.

[Effect of idea]

As described above, according to the present invention, since the mounting height of the CRT mounting body can be adjusted, it is possible to easily adjust the degree of closeness between the front surface of the CRT and the back side of the front panel of the cabinet. Moreover, the height can be adjusted by fitting the convex part of the CRT mounting part to the concave part of the CRT mounting body, or by fitting the convex part of the CRT mounting part to the concave part.
This can be done by aligning the convex part of the CRT mounting body.
When changing the combination of protrusions and recesses, if there is no guide part, you can rotate the CRT mounting body inside the CRT mounting part, or if a guide part is formed, you can do it by pulling out the CRT mounting body and making just one pitch. It's easy because you just have to shift it and then insert it again.
